I know that there's the thanks button, but sometimes I feel like using the thanks button for a certain post, that will no longer be useful to me after that such as a reply or some sort of joke, funny related pic ~ or even a tip. I do give thanks to some OP for their methods, but then again I have to search and filtrate the useful given thanks versus the amiable ones.

Having a fav button, would help us greatly on managing the threads. It's like I'd add 'these' 2 threads about some CPA method on my Fav CPA category. Then favorite some FB related thread to my Social Networks Fav category.

Hope you got my point
